GeForce RTX 3080 vs Radeon RX 5500 XT

Intro

The GeForce RTX 3080 makes use of a 8 nm design. nVidia has set the core speed at 1440 MHz. The GDDR6X RAM works at a frequency of 1188 MHz on this specific model. It features 8704 SPUs along with 272 Texture Address Units and 96 Rasterization Operator Units.

Compare all that to the Radeon RX 5500 XT, which features a clock speed of 1717 MHz and a GDDR6 memory speed of 1750 MHz. It also features a 128-bit bus, and makes use of a 7 nm design. It features 1408 SPUs, 88 Texture Address Units, and 32 ROPs.

Radeon RX 5500 XT 229376 MB/sec
Difference: 549171 (239%)

Texel Rate

The GeForce RTX 3080 is quite a bit (approximately 159%) more effective at texture filtering than the Radeon RX 5500 XT. (explain)

GeForce RTX 3080 391680 Mtexels/sec
Radeon RX 5500 XT 151096 Mtexels/sec
Difference: 240584 (159%)

Pixel Rate

The GeForce RTX 3080 will be quite a bit (more or less 152%) faster with regards to full screen anti-aliasing than the Radeon RX 5500 XT, and also capable of handling higher screen resolutions without losing too much performance. (explain)

GeForce RTX 3080 138240 Mpixels/sec
Radeon RX 5500 XT 54944 Mpixels/sec
Difference: 83296 (152%)

Please note that the above 'benchmarks' are all just theoretical - the results were calculated based on the card's specifications, and real-world performance may (and probably will) vary at least a bit.

Memory Bandwidth: Memory bandwidth is the largest amount of information (measured in MB per second) that can be moved across the external memory interface within a second. It is worked out by multiplying the card's bus width by its memory speed. In the case of DDR type memory, it should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The better the bandwidth is, the better the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that can be processed per second. This is calculated by multiplying the total amount of texture units of the card by the core clock speed of the chip. The better the texel rate, the better the card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels in one second.

Pixel Rate: Pixel rate is the maximum amount of pixels the graphics card can possibly write to the local memory per second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount of Raster Operations Pipelines by the the core clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill rate is also dependant on many other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to reach the max fill rate.
